Vasopressin (Antidiuretic Hormone). Vasopressin (arginine vasopressin, AVP; antidiuretic hormone, ADH) is a peptide hormone formed in the hypothalamus, then transported via axons to, and released from, the posterior pituitary into the blood. AVP has two principle sites of action: the kidney and blood vessels.
The Siberian cat is very exotic, but itâs kittens are adorable. A cat with a big personality and a big popularity in many parts of the world, their kittens are a big part of the reason that so many people adore this breed.
He walks right next to you like a dog and is very loyal! If you're looking for a fun and energetic cat then I suggest getting a Napoleon cross munchkin kitten/cat. Maine Coons are also a very friendly breed that will create a close bond with the owner.
